How much can I save by switching energy plans?

There are 2 common scenarios where you can save money by switching:

  • You're on a standing offer. If you've been on your plan for over a year or have moved house recently, there's a chance you're on a standing offer. The latest research indicates you could save between $180 and $300 per year by switching to a market offer.
  • You haven't compared recently. Even if you're on a market offer, there's a good chance there's something cheaper on the market since you last switched. Switching in this case can still save you money.

Regardless of your situation, all you need to do is compare energy plans available in your area to see what you can save.
